Completely butchered the novel and rewrote the entire story. Do not recommend this version at all. If your first time experiencing this story is by way of this show, you would walk away thinking the story is nothing special. But I recommend reading the book or listening to an audiobook version of the book. BJ Harrison did really a great job narrating the audiobook. Additionally, I do not understand why they wrote Sherlock Holmes in as a chacaracter. Totally don't understand the thinking behind it. This is one of Arthur Conan Doyle's works that really stands out outside of his Sherlock Holmes series. It is a pity they did it zero justice.
